Calculation of carrier swing in FM wave
A 100MHz carrier is frequency modulated by 5 KHz wave. For a frequency deviation of 100 KHz, calculate the carrier swing of the FM signal.
Options:
a) 2000 KHz
b) 100 KHz
c) 105 KHz
d) 200 KHz
Correct Answer: d) 200 KHz
Explanation:
Carrier frequency fc<.sub>= 100MHz
Modulating frequency fm= 5 KHz
Frequency deviation Δf = 100 KHz
Carrier swing of the FM signal = 2* Δf
= 2* 100
= 200 KHz
